Abstract
Description
Die Erfindung betrifft eine Trennhülse nach dem Oberbegriff des ersten Anspruchs. Trennhülsen der hier betrachteten Art werden verwendet, um Räume hermetisch voneinander zu trennen, in denen unterschiedliche Medien und/oder unterschiedliche Drücke vorliegen. Beispielsweise finden sie Verwendung in Magnetkupplungen, beispielsweise in Vakuumpumpen. Solche Magnetkupplungen erlauben es, den Pumpeninnraum, in dem sich beispielsweise Öl zum Dichten und Schmieren befindet, vom Antrieb zu trennen. Damit wird es möglich, die Pumpen auch dort einzusetzen, wo Kontamination mit Ölresten vermieden werden muss.The The invention relates to a separating sleeve according to the preamble of the first claim. Separating sleeves of Types considered here are used to make spaces hermetically different from one another separate, where different media and / or different pressures are present. For example, they find use in magnetic clutches, for example in vacuum pumps. Such magnetic couplings allow the pump interior, in which, for example, oil for Dense and lubricating is to disconnect from the drive. This will be it is possible to use the pumps also where contamination with oil residues must be avoided.
Im Stand der Technik sind die beiden im folgenden beschriebenen Herstellungsvarianten für solche Trennhülsen bekannt.in the State of the art are the two manufacturing variants described below for such isolating sleeves known.
Die
Die
Die im Stand der Technik vorgeschlagenen Lösungen sind zusammengefasst aufwändig, teuer und bieten Gefahren in Bezug auf Lecks, da keine durchgehenden Materialstücke vorhanden sind, bzw. die Trennhülsen aus einer Vielzahl von Teilen bestehen.The Solutions proposed in the prior art are summarized consuming, expensive and offer hazards in terms of leaks, as there are no continuous material pieces are present, or the separating sleeves consist of a variety of parts.
Aufgabe ist es daher, eine hermetisch dichte Spalthülse zu entwickeln, die aus preiswertem Material herstellbar ist und die weiteren Nachteile des Standes der Technik vermeidet.task It is therefore, to develop a hermetically sealed split sleeve, which inexpensive material can be produced and the other disadvantages of the prior art avoids.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei der Anordnung mit einer hermetisch dichten Trennhülse mindestens eine der Oberflächen der Trennhülse eine die Ausbildung von Wirbelströmen reduzierende Gestalt besitzt.These Task is inventively characterized solved, that in the arrangement with a hermetically sealed separating sleeve at least one of the surfaces the separating sleeve has the formation of eddy currents reducing shape.
Da die Gestalt wenigstens einer der Oberflächen geeignet ist, die Ausbildung von Wirbelströmen zu reduzieren, wird die auftretende Verlustwärme deutlich herabgesetzt. Daher ist es möglich, kostengünstigere Materialien einzusetzen, insbesondere Metalle.There the shape of at least one of the surfaces is suitable, the training of eddy currents too reduce the occurring heat loss is significantly reduced. Therefore, it is possible cost-effective Use materials, especially metals.
In einer ersten Weiterbildung der Erfindung wird die Struktur auf der Oberfläche durch eine Unterteilung in axiale Flächenabschnitte erreicht. Solche Unterteilung können beispielsweise durch Drehen und Fräsen der Oberfläche leicht hergestellt werden.In A first development of the invention, the structure of the surface achieved by a division into axial surface sections. Such subdivision can for example, by turning and milling the surface easily getting produced.
In
einer nächsten
Weiterbildung ist die Hülse über mehrere
axiale Flächenabschnitte
hinweg einstückig
ausgebildet. Hierdurch werden Trennflächen zwischen Hülsenabschnitten
wie beispielsweise im Stand der Technik
In einer nächsten Weiterbildung wird die Struktur dadurch erzeugt, dass Vertiefungen mit einem dreieckigen Querschnitt eingedreht werden. Auch ein rechteckiger Querschnitt der Vertiefungen ist denkbar und führt zur Lösung. Beide Varianten sind besonders einfach herzustellen.In one next Continuing, the structure is created by making recesses be screwed with a triangular cross-section. Also a rectangular one Cross-section of the recesses is conceivable and leads to the solution. Both variants are especially easy to make.
Ein weiteren Ausführungsform ist wenigstens eine der Oberflächen der Trennhülse mit einer elektrisch isolierenden Schicht versehen. Kurzschlüsse zwischen verschiedenen Flächenabschnitten und eine dadurch bedingte Zunahme der Wirbelströme können so vermieden werden.One another embodiment is at least one of the surfaces the separating sleeve provided with an electrically insulating layer. Short circuits between different surface sections and a consequent increase in the eddy currents can be avoided.
Insbesondere ermöglicht die Beschichtung, die Hülse wie einen Wellschlauch zu formen und über die axiale Länge zusammenzustauchen, so dass die Flächenabschnitte aufeinander zu liegen kommen. Die Stabilität dieser Hülse wird deutlich erhöht.Especially allows the coating, the sleeve how to shape a corrugated tube and compress it over the axial length, so that the surface sections come to rest on each other. The stability of this sleeve is significantly increased.
In einer weiteren Ausführungsform weist die Trennhülse an einem axialen Ende einen fest und hermetisch dicht mit ihr verbundenen Deckel auf, so dass ein Topf entsteht. Solch ein Topf kann vorteilhaft in einer Magnetkupplung eingesetzt werden.In a further embodiment has the separation sleeve at one axial end a firm and hermetically sealed to her Cover so that a pot is formed. Such a pot can be beneficial in a magnetic coupling can be used.
Besonders vorteilhaft wird solch eine Hülse in einer Vakuumpumpe zum Trennen zweier Räume eingesetzt. In einer ölgedichteten Drehschiebervakuumpumpe entsprechen diese Räume zum einen dem Pumpeninnenraum mit dem Pumpsystem und zum anderen der Pumpenumgebung.Such a sleeve is used particularly advantageously in a vacuum pump for separating two spaces. In an oil-sealed rotary vane vacuum pump, these spaces correspond to the one Pump interior with the pumping system and on the other hand the pump environment.
Anhand von Ausführungsbeispielen soll die Erfindung verdeutlicht und weitere vorteilhaften Eigenschaften dargestellt werden.Based of exemplary embodiments the invention should be clarified and other advantageous properties being represented.
